What is Double Glazing?

Double Glazing

Installing double glazing in your home can have a number of benefits, from improved energy efficiency to increased security. Here we take a look at some of the top reasons why you should consider having double glazed windows installed in your property.


Double glazing is a type of window that has two panes of glass, with a space in between them. This space is usually filled with an inert gas like argon or krypton, which helps to improve the insulation of the window. Double glazing can be used on both windows and doors, and is an effective way of reducing heat loss in a property.

Benefits of Double Glazing​

There are a number of benefits to installing double glazing in your home, including:


Improved energy efficiency: Double glazed windows can help to reduce heat loss in your property, which means you’ll be able to keep your home warmer for longer. This can lead to lower energy bills, as you won’t need to use your heating as much to keep your home at a comfortable temperature.

Increased security: Double glazed windows are more difficult to break than single paned windows, which makes them more secure. This can give you peace of mind knowing that your property is better protected against burglars and vandals.

Improved comfort: Double glazed windows can help to reduce noise from outside, making your home more peaceful and enjoyable to live in.

Reduced condensation: Double glazing can help to reduce condensation on your windows, as the inner pane of glass stays warmer than the outer pane. This can help to improve the appearance of your windows, and make your home more comfortable.

What are the different types of double glazing available

There are two main types of double glazing available:

1. Standard double glazing: This is the most common type of double glazing, and consists of two panes of glass with a space in between them. The space is usually filled with argon gas, which helps to improve the insulation of the window.

2. Low-emissivity (Low-E) double glazing: This type of double glazing has a special coating on the inner pane of glass, which reflects heat back into the room. Low-E double glazing is more energy efficient than standard double glazing, and can help to reduce your energy bills even further.

How do you install double glazing in your home

Installing double glazing is a job that should be carried out by a qualified tradesperson. They will measure your windows and doors to make sure they fit correctly, and then install the double glazing units into your property.


How much does double glazing cost?

There are a number of factors that can affect the cost of double glazing, including the size and type of window, and whether you choose standard or low-emissivity glass. Double glazing typically costs between $650 to $1400 per sqm.

Is double glazing worth the price?

The initial cost of double glazing may be higher than single glazed windows, but over time you will see the benefits in lower energy bills and a more comfortable home. Double glazing is also a more secure type of window, which can give you peace of mind.

How long does double glazing last?

When installed correctly, double glazing can last for 20 years or more. The lifespan of double glazing will depend on a number of factors, including the type of glass and the quality of the installation.

Which is better double glazing or secondary glazing?

Secondary glazing is an additional pane of glass that is installed on the inside of your window, over existing single glazing. Double glazing is a more effective way of insulating your home, as it has two panes of glass with a space in between them which is filled with an inert gas. However, secondary glazing can be a more cost-effective option if you’re not able to replace your existing windows.
